The information processing device includes a card processing section that communicates with an IC chip of an IC card (card IC chip), and when security is satisfied between the information processing device and the card IC chip, performs information processing function of the card IC chip. Authentication processing between an IC chip (terminal IC chip) of the portable terminal and the card IC chip is performed through the card processing section, and secure communication is provided between the terminal IC chip and the card IC chip through the card processing section when the authentication processing is successful. Information input on the portable terminal is transmitted to the card IC chip through the secure communication. In this way, high user convenience can be achieved and increased security can also be achieved for the entire system.

TECHNICAL FIELD

The present invention relates to an information processing system including an information processing device and a portable terminal, and in particular to a technique for sending information input on a portable terminal to an IC chip in an IC card, which is to be processed by an information processing device.

BACKGROUND ART

Some IC cards have a credit function (for example, credit card) and others are entry cards for entry control to a room. Such IC cards can be used for settlement processing (for example, payment at the register in a shop or the like). In general, the settlement processing with an IC card involves inputting personal identification number (PIN) information.

Conventional information processing devices, such as a POS terminal, have a connection to an input pad or a key device placed near a door for inputting a personal identification number to open a lock, which allow the use of numeral keys to input a personal identification number. The personal identification number input on the input pad or the like is sent from the information processing device to an IC card. In the IC card, the personal identification number is collated and when it is confirmed that security is satisfied, the settlement processing or unlocking processing are performed (for example, see Patent Literature 1).

In a conventional system, however, if the input pad or the information processing device is tampered, a third party will allowed to obtain important information (PIN information) and security of the system will failed. In addition, a conventional input pad is connected to the information processing device with a cable and is difficult to use (for example, to pay at the register in a shop) at a distance from the information processing device, which reduces user convenience.

The information processing system of the present invention is an information processing system including an information processing device and a portable terminal, the information processing device including: a card processing section that communicates with a card IC chip, which is an IC chip provided on an IC card, and when security is satisfied between the information processing device and the card IC chip, performs information processing function of the card IC chip; an authentication processing section that performs authentication processing between a terminal IC chip, which is an IC chip provided on the portable terminal, and the card IC chip through the card processing section; and a secure communication section that provides secure communication between the terminal IC chip and the card IC chip through the card processing section when the authentication processing is successful, wherein information input on the portable terminal is transmitted to the card IC chip through the secure communication.

With this configuration, authentication processing between the card IC chip and the terminal IC chip is performed, and when the authentication processing is successful (successful authentication), secure communication is provided between the card IC chip and the terminal IC chip. Then, information (for example, PIN information) input on the portable terminal (for example, a mobile phone) is transmitted to the card IC chip through the secure communication (encrypted communication). Since information can be transmitted from the portable terminal to the IC card through the secure communication in this way, highly confidential information (for example, PIN information) can be sent confidently.

In this case, since the user can use his/her portable terminal to input information at a distance from the information processing device, high user convenience is achieved. In addition, since a conventional input pad is not needed, a third party cannot illegally obtain the information. Further in this case, although the information processing device intervenes between the portable terminal and the IC card, security between the information processing device and the IC card is assured. In addition, information sent through the information processing device is one that is sent through secure communication, namely one that is encrypted. Consequently, even if a third party was able to illegally obtain the information from the information processing device, the third party could not decrypt the information. In this way, increased security can be achieved for the entire system.

First Embodiment

A configuration of a first embodiment of information processing system of the invention will now be described with reference to the drawings. FIG. 1 is a diagram for illustrating a configuration of an information processing system according to the first embodiment. As shown in FIG. 1, the information processing system includes an information processing device 2, such as a POS terminal, and a portable terminal 3, such as a mobile phone. The information processing device 2 includes a card slot section 5 for receiving an inserted IC card 4. The IC card 4 is a credit card that has a credit function.

The information processing device 2 also includes a card processing section 6. The card processing section 6 communicate with an IC chip (card IC chip 7) of the IC card 4 in a contact manner while the IC card 4 is inserted in the card slot section 5 and when it is confirmed that security is satisfied between the information processing device and card IC chip 7, perform information processing function of the card IC chip 7. Accordingly, while the IC card 4 is inserted in the card slot section 5, various functions of the card IC chip 7 can be executed by the information processing device 2. In other words, while the IC card 4 is inserted in the card slot section 5, various functions of the card IC chip 7 may be considered to be provided to the information processing device 2.

The card IC chip 7 includes an authentication processing section 8, a secure communication section 9, a collation processing section 10, and a read/write permitting section 11. The authentication processing section 8 has a function of performing authentication processing between an IC chip (terminal IC chip 12) of the portable terminal 3 and the card IC chip through the card processing section 6. The authentication processing is for confirming that they are communicating with a correct counterpart each other. When the authentication processing is successful (successful authentication), confidential information is shared between the card IC chip 7 and the terminal IC chip 12. The secure communication section 9 has a function of providing secure communication with the terminal IC chip 12 through the card processing section 6 when the authentication processing is successful. The function sets up a communication channel (also referred to as a virtual communication channel or a secure path) that is encrypted based on the confidential information shared between the card IC chip 7 and the terminal IC chip 12, and the communication channel can be used to provide secure communication. Information such as PIN information input on the portable terminal 3 is sent to the card IC chip 7 through the secure communication.

The collation processing section 10 has a function of performing collation processing using the PIN information input on the portable terminal 3. The portable terminal 3 includes an input section 13, such as numeral keys or a touch panel. The user of the portable terminal 3 inputs information such as PIN information from the input section 13. The read/write permitting section 11 has a function of permitting reading from/writing to the card IC chip 7 when the collation processing is successful (successful collation). Specifically, the reading/writing is settlement processing in the IC card 4.

The information processing device 2 includes a server communication section 15 that communicates with a settling server 14. The server communication section 15 has a function of transmitting result information of settlement processing performed in the card IC chip 7 (settlement information) to the settling server 14. The settling server 14 is an external server constituting a settlement system and has a function of using the settlement information sent from the portable terminal 3 to perform settlement processing in the IC card 4.

The terminal IC chip 12 is composed of an SIM chip or a security processing chip. The terminal IC chip 12 may have a function of performing settlement processing, and in this case, the terminal IC chip 12 may be considered to be an IC chip intended for settlement processing.

The terminal IC chip 12 includes an authentication processing section 16 and a secure communication section 17. The authentication processing section 16 has a function of performing authentication processing between the terminal IC chip and the card IC chip 7 through the card processing section 6. The secure communication section 17 has a function of providing secure communication with the card IC chip 7 through the card processing section 6 when the authentication processing is successful (successful authentication). The PIN information obtained from the input section 13 is sent to the information processing device 2 through the secure communication.

FIG. 2 shows a variation of the information processing system 1 according to the embodiment (a variation of information processing device 2). As shown in FIG. 2, the information processing device 2 includes a card hover section 20 for the user to hold the IC card 4 up over the section.

In this case, the card processing section 6 has a function of communicating with the card IC chip 7 in a non-contact manner while the IC card 4 is held up over the card hover section 20 and when security is satisfied between the information processing device and the card IC chip 7, performing information processing function of the card IC chip 7. Accordingly, while the IC card 4 is held up over the card hover section 20, various functions of the card IC chip 7 can be executed by the information processing device 2. In other words, while the IC card 4 is held up over the card hover section 20, various functions of the card IC chip 7 may be considered to be provided to the information processing device 2.

It should be noted that the card hover section 20 may be provided with a support member for supporting the IC card 4. In this case, the position of the IC card 4 that is held up can temporarily be fixed relative to the card hover section 20. A proper positional relationship between the two is thus maintained, and thereby the non-contact communication as described above can be performed more reliably.

FIG. 3 shows a further variation of the information processing system 1 according to the embodiment (a variation of portable terminal 3). As shown in FIG. 3, the portable terminal 3 includes two terminal chips (a SIM chip 30 and a security processing chip 31) and a selector 32.

The SIM chip 30 has a function of mainly allowing the use of a telephone. The SIM chip 30 includes, for example, a chip mounted on an SIM card provided by a telephone carrier, which has stored therein a specific number associated with a telephone number. One example of such SIM card is a universal subscriber identity module (USIM) card adopted for the third generation mobile phone. The SIM chip may also includes an authentication processing section and a secure communication section.

The security processing chip 31 has a function of mainly assuring security. For example, the security processing chip 31 includes a CPU and a memory, and has a secure structure for the CPU and the memory in terms of a physical, electrical, or software aspect. The security processing chip 31 includes an ISO/IEC 14443 type A or type B based electronic settlement IC chip, an IC chip mounted on an IC identification, FeliCa (registered trademark) chip, and the like. Similarly to the SIM chip, the security processing chip 31 may also includes an authentication processing section and a secure communication section.

The selector 32 has a function of selecting either one of the SIM chip 30 and the security processing chip 31 as the terminal IC chip 12 to be processed with the card IC chip 7. The selector 32 corresponds to the chip selecting section.

For example, the selector 32 makes a comparison between the security level of the SIM chip 30 and the security level of the security processing chip 31, and selects one that has a higher security level as determined by the comparison as the terminal IC chip 12 to be processed with the card IC chip 7. Security level information (for example, “high”, “moderate”, “low”, or the like) is preset to each of the SIM chip 30 and the security processing chip 31.

Alternatively, the selector 32 makes a comparison between the processing speed of the SIM chip 30 and the processing speed of the security processing chip 31, and selects one that has a higher processing speed as determined by the comparison as the terminal IC chip 12 to be processed with the card IC chip 7. Processing speed information (for example, “high”, “moderate”, “low”, or a numeral value that may be used as an indicator of a processing speed, or the like) is preset to each of the SIM chip 30 and the security processing chip 31.

Furthermore, processes may be distributed between the SIM chip 30 and the security processing chip 31 on the basis of a function that the selector 32 processes. For example, this applies to the case where settlement applications are handled by the SIM chip 30 and encryption and management for cryptographic keys are handled by the security processing chip 31.

It should be noted that the terminal IC chip 12 to be processed with the card IC chip 7 may be selected (statically selected) by the user of the portable terminal 3 in advance as either one of the chips or may be automatically selected (dynamically selected) depending on the operational condition of each chip. For example, the dynamic selection is made based on processing speed values obtained by the selector 32 causing internal CPUs (not shown) in the card IC chip 7 and the terminal IC chip 12 to calculate trial data (the processing speed value represents a possible number of calculations per second or quantized versions of the possible number of calculations). The dynamic selection is also made based on information (operational clock frequency, operational bit length, or the like) of the respective internal CPUs read from the card IC chip or the terminal IC chip by the selector 32.

The operation of the information processing system 1 thus configured will now be described with reference to a sequence diagram in FIG. 4. Here, a scenario where payment is made at the register in a shop will be illustrated as an example.

When payment is made at the register in a shop, a clerk first registers a product that the user intends to buy with a POS terminal (information processing device 2). Once the total amount of purchase is displayed on the POS terminal, the user sets an electronic money card (IC card 4) on the information processing device 2 (i.e. inserts the card into the card slot section 5). In addition to a prepaid card, the electronic money card may be any card such as a postpaid card, a debit card, and credit card. The user then inputs personal identification number (PIN) information from his/her own portable terminal 3 at hand.

In this case, as shown in FIG. 4, in the information processing system 1, the PIN information input is first accepted on the portable terminal 3 (S1), and then the terminal IC chip 12 to be used is selected based on a security level or a processing speed (S2).

Subsequently, authentication processing between the terminal IC chip 12 and the card IC chip 7 is performed (S3), and when the authentication processing is successful, an encrypted communication channel (secure path) is established between the terminal IC chip 12 and the card IC chip 7 based on confidential information shared between the terminal IC chip 12 and the card IC chip 7 (S4). Then, the PIN information is transmitted from the terminal IC chip 12 to the card IC chip 7 through secure communication (encrypted communication) (S5).

In the card IC chip 7, collation processing is performed by using the PIN information received from the terminal IC chip 12 (S6), and when the collation processing is successful, settlement processing is performed in the IC card 4 (S7).

Next, authentication processing between the information processing device 2 and the settling server 14 is performed (S8), and when the authentication processing is successful, a secure path is established between the information processing device 2 and the settling server 14 (S9). Subsequently, result information of settlement processing (settlement information) is transmitted from the information processing device 2 to the settling server 14 through secure communication (encrypted communication) (S10). In settling server 14, then, settlement processing is performed by using the settlement information (S11).

According to the information processing system 1 of the embodiment of the invention, high user convenience can be achieved and increased security can also be achieved for the entire system.

In other words, in the embodiment, authentication processing between the card IC chip 7 and the terminal IC chip 12 is performed, and when the authentication processing is successful (successful authentication), secure communication is provided between the card IC chip 7 and the terminal IC chip 12. Then, information (for example, PIN information) input on the portable terminal 3 (for example, a mobile phone) is transmitted to the card IC chip 7 through the secure communication (encrypted communication). Since information can be transmitted from the portable terminal 3 to the IC card 4 through the secure communication in this way, highly confidential information (for example, PIN information) can be sent confidently.

In this case, since the user can use his/her portable terminal 3 to input information at a distance from the information processing device 2, high user convenience is achieved. In addition, since a conventional input pad is not needed, a third party cannot illegally obtain the information. Further in this case, although the information processing device 2 intervenes between the portable terminal 3 and the IC card 4, security between the information processing device 2 and the IC card 4 is assured. In addition, information sent through the information processing device 2 is one that is sent through secure communication, namely one that is encrypted. Consequently, even if a third party was able to illegally obtain the information from the information processing device 2, the third party could not decrypt the information. In this way, increased security can be achieved for the entire system.

In the embodiments, when collation processing using information input on the portable terminal 3 is successful (successful collation), reading from/writing to the card IC chip 7 is permitted. In this way, the information input on the portable terminal 3 can be used to determine whether the use of the card IC chip 7 should be permitted or not.

Specifically, when the collation processing using PIN information is successful (successful collation), settlement processing in the IC card 4 is permitted. In this way, the PIN information input on the portable terminal 3 can be used to determine whether settlement processing in the IC card 4 should be permitted or not.

In the embodiments, the SIM chip 30 or the security processing chip 31 provided on the portable terminal 3 can be used to provide secure communication with the IC card 4.

Further, in the embodiments, the processing result information (settlement information) obtained from the card IC chip 7 can be transmitted from the information processing device 2 to the settling server 14 to use the information in settlement processing in the IC card 4.

In the embodiments, although description has been made to the case where the settlement information is transmitted from the information processing device 2 to the settling server 14, the settlement information may be transmitted from the portable terminal 3 to the settling server 14. For example, the settlement information may be sent from the information processing device 2 to the portable terminal 3 through secure communication and then sent from the portable terminal 3 to the settling server 14 through secure communication.

In a variation of the embodiment (a variation shown in FIG. 3), the portable terminal 3 is provided with both the SIM chip 30 and the security processing chip 31, and in this case, one of the chips can be used to provide secure communication with the IC card 4.

For example, one of the chips that has a higher security level can be used to provide secure communication with the IC card 4. Alternatively, one of the chips that has a higher processing speed can be used to provide secure communication with the IC card 4.

Second Embodiment

FIG. 5 shows an example of an information processing system 51 according to a second embodiment. As shown in FIG. 5, the information processing device 52 is an entry control system that includes a card hover section 20 for the user to hold the IC card 4 up over the section.

The information processing device 52 communicates with an entry control server 54 that stores entry conditions, and causes the card processing section 6 to identify whether information in the IC card 4 that is held up meets the entry conditions or not. When the information in the card 4 (for example, employee number that identifies an individual) meets the entry conditions, the information processing device 52 issues an instruction to a lock control section 56 to open a lock and a lock 57 is opened.

In this case, the card processing section 6 has a function of communicating with the card IC chip 7 in a non-contact manner while the IC card 4 is held up over the card hover section 20 and when security is satisfied between the information processing device and the card IC chip 7, performing information processing function of the card IC chip 7.

It should be noted that the card hover section 20 may be provided with a support member for supporting the IC card 4. In this case, the position of the IC card 4 that is held up can temporarily be fixed relative to the card hover section 20. A proper positional relationship between the two is thus maintained, and thereby the non-contact communication as described above can be performed more reliably.

Although the portable terminal 3 includes a terminal IC chip 12, a SIM chip 30 and a security processing chip 31 and a selector 32 may be provided similarly to the portable terminal shown in FIG. 3. In this case, as in the case of FIG. 3, the SIM chip 30 has a function of mainly allowing the use of a telephone, the SIM chip 30 includes, for example, a chip mounted on an SIM card provided by a telephone carrier, which has stored therein a specific number associated with a telephone number, and the SIM chip may also includes an authentication processing section and a secure communication section.

The information processing system 51 thus configured will now be described with reference to a sequence diagram in FIG. 6. Here, a scenario where a person enters and exits a room where security should be maintained will be illustrated as an example.

When the person tries to enter the room, he/she holds his/her card 4 up over the card hover section 20 connected to the information processing device 52. The card hover section 20 detects the card 4 when it is ready for communication with the card 4 or by a proximity sensor provided on a surface to which the card is touched and waits for PIN information.

The person inputs personal identification number (PIN) information from his/her own portable terminal 3 at hand. At this time, in the information processing system 51 of the embodiment, the information processing device 52 first enters a waiting state for PIN information in response to a signal from the proximity sensor or the like, as shown in FIG. 6. Thereafter, the portable terminal 3 accepts PIN information input (S1). Subsequently, in the case where the portable terminal includes a selector 32 and two chips as shown in FIG. 3, the terminal IC chip to be used is selected based on a security level or a processing speed. In the case of a single terminal IC chip 12, step S2 is omitted (S2).

Subsequently, authentication processing between the terminal IC chip 12 and the card IC chip 7 is performed (S3), and when the authentication processing is successful, an encrypted communication channel (secure path) is established between the terminal IC chip 12 and the card IC chip 7 based on confidential information shared between the terminal. IC chip 12 and the card IC chip 7 (S4). Then, the PIN information is transmitted from the terminal IC chip 12 to the card IC chip 7 through secure communication (encrypted communication) (S5).

In the card IC chip 7, collation processing is performed by using the PIN information received from the terminal IC chip 12 (S6), and when the collation processing is successful, entry and exit approval processing is performed (S45).

Next, authentication processing between the information processing device 2 and the entry control server 14 is performed (S8), and when the authentication processing is successful, a secure path is established between the information processing device 2 and the entry control server 54 (S9). Subsequently, result information of entry and exit approval processing (entry and exit information) is transmitted from the information processing device 2 to the entry control server 54 through secure communication (encrypted communication) (S60). The entry and exit information is then updated and entry and exit processing is performed in the entry control server 54 (S46).

According to the entry and exit system 1 of the embodiment of the invention, high user convenience can be achieved. As in the case of the first embodiment, increased security can also be achieved for the entire system.

Embodiments of the present invention have been described above by way of example. The scope of the invention, however, is not limited thereto and alterations and modifications may be made as required without departing from the scope of the appended claims.

Although presently preferred embodiments of the invention have been described above, it is to be understood that various modifications may be made to the embodiments thereof and the appended claims are intended to encompass all such modifications that fall within the scope of the true spirit and scope of the invention.
